Texas Instruments TLV9022PWR

Overview

TLV9022PWR from Texas Instruments is a dual-channel, open-drain precision comparator with rail-to-rail fault-tolerant inputs, 300 µV max input offset voltage, 100 ns typical propagation delay, and 16 µA per channel quiescent current. It operates from 1.65 V to 5.5 V and supports industrial temperature range (–40°C to +125°C), enabling precise voltage monitoring in motor drive overcurrent detection circuits.

For engineers reviewing the TLV9022PWR datasheet, TLV9022PWR pinout, TLV9022PWR application, or TLV9022PWR equivalent, key selection criteria include open-drain output compatibility with mixed-voltage logic translation, input fault tolerance up to 6 V beyond supply rails, low-power operation for battery-backed systems, and SOIC-8 package suitability for automated PCB assembly.

Technical Context

The TLV9022PWR implements a high-speed, low-power comparator architecture optimized for precision threshold detection under noisy industrial conditions. Its input stage withstands overvoltage transients up to 6 V relative to V– without phase inversion or damage, and its open-drain output allows flexible pull-up to voltages below or above V+, supporting level-shifting between 1.8 V, 3.3 V, and 5 V domains.

Each comparator channel features independent input bias current of 5 pA and input offset voltage drift of ±0.5 µV/°C across –40°C to +125°C, ensuring stable trip-point accuracy in thermally varying environments such as factory automation sensor interfaces and appliance control boards.

FAQ

What is the maximum input voltage the TLV9022PWR can tolerate without damage?

The TLV9022PWR inputs tolerate voltages from –0.3 V to +6 V referenced to V–, regardless of the V+ supply voltage. This fault tolerance eliminates external clamping diodes in applications with transient overvoltages, such as industrial sensor front-ends or motor current sense amplifiers. The TLV9022PWR maintains correct output polarity and avoids phase inversion even when inputs exceed V+ by up to 1 V.

Does TLV9022PWR support operation from a 1.8 V supply?

Yes, TLV9022PWR is fully specified from 1.65 V to 5.5 V supply range. At 1.8 V, it delivers 100 ns typical propagation delay and maintains 300 µV input offset voltage, enabling use in low-voltage IoT edge nodes and portable medical devices. Quiescent current remains at 16 µA per channel, preserving battery life in always-on monitoring functions implemented with TLV9022PWR.

Can TLV9022PWR outputs drive LEDs directly?

No - TLV9022PWR has open-drain outputs that sink current only and cannot source current. To drive an LED, connect the anode to a positive supply (≤6 V) and the cathode to OUT1 or OUT2; the LED illuminates when the comparator asserts low. For sourcing capability or higher drive strength, TI's TLV9032 (push-pull version) is recommended instead of TLV9022PWR.

What is the thermal pad connection requirement for TLV9022PWR in SOIC-8 package?

The TLV9022PWR in SOIC-8 (PWR suffix) does not include an exposed thermal pad - that feature applies only to the DSG (WSON-8) variant. For SOIC-8, standard PCB copper pour under the package is sufficient. Thermal resistance θ_JA is 167.7°C/W, so at 32 µA total quiescent power (16 µA × 2 channels × 5 V), junction-to-ambient rise is negligible (<0.02°C), making heatsinking unnecessary for TLV9022PWR in normal operation.

How does TLV9022PWR handle input common-mode voltage beyond the supply rails?

TLV9022PWR inputs are explicitly rated for common-mode voltages from (V–) – 0.2 V to (V+) + 0.2 V, and fault-tolerant up to +6 V relative to V–. This allows direct connection to signals like 5.7 V battery monitors on a 5 V system or 24 V field inputs attenuated to 4.8 V - all without external resistive dividers or protection. The internal ESD clamps and input stage design ensure no output phase inversion occurs, preserving functional safety in TLV9022PWR-based supervision circuits.
